You do realize that there is a difference between gifts and offerings and the tithe don't you. The ten percent belongs to God...Thus giving tithe is not a gift. However a gift,or an offering is given out of the other ninety percent that belongs to you.
I do not see where tithing is required in the New Covenant but the principle applies...If you give tithes to God, it becomes the key to receiving all blessings
Malachi 3:10
Bring the whole tenth
into the storehouse, so that there will be food in my house, and put me to the test,” says
Adonai-Tzva’ot. “See if I won’t open for you the floodgates of heaven and pour out for you a blessing far beyond your needs.
Yes this is Old Covenant but its a principle that still applies If you will give tithe...God will bless to the point where you cannot contain it all
So the question remains......Can you afford not to title? Really?
